GPU and CPU load

[Fast.n.painful]

Hi, for some reason game is using 3% of CPU and 99% of GPU.
I9-12900k and rtx4090. Stable fps and all, but my card goes to 70c in game, when it usually stays at 60c in most games.

That is exactly what you want. Lower GPU usage often is linked to CPU bottlenecks or other bottlenecks either in your system or the game optimization. You can lower GPU usage by capping the FPS or use VSYNC.

-Reduce GPU demanding settings
-Increase CPU demanding settings
-Cap your frame-rate with RivaTuner. Few games benefit from having an uncapped frame-rate. A variable frame-rate will mess up your aim and timing and running at 100% GPU usage will kill your GPU over time. Any decrease in input lag is not worth it.

It also may be a bug, I've heard some hardware configurations aren't displaying CPU usage correctly.

That is kinda odd. I have a 5800X that's overclocked and an RTX 3080 on max settings and this is one of those games that runs cooler on my PC. It utilizes both my CPU and GPU somewhat evenly as well.

I don't know, usually games use 20% cpu and 90% gpu with average t' around 50c for cpu and 60c for gpu. But this game heats up gpu to 70c without a reason

Alright, put it this way. If you uncap your frame-rate your frame-rate is going to go up until either your CPU usage hits 100% or your GPU usage hits 100%. If your CPU is capable of 240 fps and you're running at 4k/60 fps then you're CPU is barely going to be used at all because it's capable of 240 fps and it's only being used for 60 fps. This is especially true of games that aren't demanding on the CPU like this one. The most GPU demanding setting by far is resolution, so if you continually lower your resolution then your frame-rate will go up until your CPU finally hits 100%. At this point lowering your resolution will decrease GPU usage, but won't increase frame-rate. However, you never want 100% CPU usage because it will stutter if you're bottlenecked by your CPU instead of your GPU.

Ideally you would want about 80% usage on both the CPU and the GPU because then you're getting the most frames out of both while not stressing them too much. You also want a locked frame-rate so that you're timing isn't messed up. 100% GPU usage also sometimes causes input lag in certain games, so always cap your frame-rate with RivaTuner.

Also, I don't know why you're worried about 70 degrees, maximum is generally 83 degrees.

Well if the game is running fine I wouldn't worry about it. You're no where near thermal throttling temperatures for that beast of a card. I think max temp before it starts throttling for even shutting down is 100°. Even the 3000 series don't start thermal throttling until 93°C. Anywhere between 70°C~75°C is pretty standard nowadays.

Yeah very few games have managed to push my GPU and CPU temps over 70C, but this game consistently has me sitting around 75C even with the framerate capped to 60 and CPU limited to 99% so it doesnt turbo.
It IS Summer here, but that would only account for an additional 1-2C since I keep my computer room reasonably cool.

Just tested Witcher 3 4.0: maxed out, 3440x1440, MAX RT and DLSS 3.0 - 65-90fps and 65c maxtemp of GPU. Maybe High on Life mines in the background?

This game is weird, it tanks my frames in 4k on a 3080. it dips to 45 in the main city.
a card that can handle 4k game in UE4 easily.
While it constantly hits 200 in 1080/2k

something is off for real.

And to be honest, there is nothing really beautiful or demanding in this game, so I don't get why it uses more resources than most games

honestly would not be surprised. High on Life has pretty good performance for me, like I sit mostly above 120fps if my framerate is unlocked with no real frame drops, so the fact that both my CPU and GPU are still getting that hot despite a 60fps lock is really concerning.

low cpu usage in a video game = good thing
high gpu usage in a video game = good thing

high cpu usage in a video game = bad thing
low gpu usage in a video game = bad thing

Amen!

The cpu is like the steering wheel whereas the GPU is like the engine below the ship

If you ever use a benchmark tool that can run a graphics benchmark on the cpu itself its hilarious how slow it is. its like 1 frame per second (and im not talking about integrated graphics inside the cpu which can run the test just fine at decent fps, im talking about rendering video using just the cpu)
